Bluetooth suddenly stopped to work with 22.04 on Dell XPS 13 9310

I've been using Ubuntu for more than one year without any problem. But now I'm facing two !

I was able to normally turn ON/OFF my bluetooth and to connect my computer to any device. But now, if the bluetooth parameter is still available, there is no way I can turn it ON. The switcher switcher, but does not turn orange and the bluetooth stays OFF.

I tried to boot on a flas drive with Ubuntu on it, the problem was the same : the bluetooth did not work (but I didn't face any sleep mode-wake up issue).

I do not understand, since my bluetooth used to work until now...

What can I do to get it back working ?

Thanks in advance for your help, nans

This is what I tried without any good result : (My bluetooth device is ON in the BIOS menu)

nans@nansXPS13:~$ rfkill list

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
